It's been resourced for longer than 3 years. There must have been a least a year's worth of work (manpower and money) gone into the MM investigation before HCW went public with it in June 2020, don't you think. So 4, possibly even 5 years already. That's a long time to still be at the stage where they can't, with confidence, charge. And I'm basing that on HCW's own relatively recent words - the quote's somewhere on the thread - where he more or less said as much, not to be expecting a MM charge anytime soon...
Not that I'm saying one has anything to do with the other (I know they don't), but I wonder if successful conviction on the pending cases (HazelB in particular, and the 2 child ones) might drive what happens next in terms of ongoing resourcing of the MM case against CB - ie. that a conviction might give weight to further resourcing being greenlit? That one might impact the other? And vice versa, as per what
@RichardKimble says above (#364) re OG's scaling back?
Although as you say, what could they be looking for/at at this stage? I really can't imagine other than living off hope that something will turn up and persistence will eventually pay off.
